Log Files

By default, IIS services create log files in the Windows directory, usually in \Winnt\System32\LogFiles. The Web service log files are in subfolder W3SVC1 and are named exyymmdd.log, where yymmdd are digits indicating the current date. A new log file is created on any day on which Web server activity occurs.

The FTP service follows a similar format, storing its log files in \Winnt\System32\MSFTPSVC1.
